I Our invention relates to a portable means for creating and directing avaporized spray of Water upon a vegetable rack or'thelike.

The objects of our inventionare to provide 5 a device of this classWhich isneyv, novel,

' practical and of utility; which Willbe serviiceable prim'arily togreen grocers, florists,

and the like; whichvvill. create a vaporized mist-like spray of Waterfor the coolingfof' vegetables, fruits or cut flowers, and which willdirect such spray as -desired a device which will be portable; vvhichmayreadily be moved from place to place in or about a store; which in itspreferred embodiment will contain its own Water supply which may leefurnished by buckets instead of a water supply system; ,Which' willeliminatefihe plumbing and Water pipesincident to usual sprays;Which'vvill. be-adjustable invheight in orderthat shelves or trays ofvarying heights may be sprayedywhich vvill use but asmall quantity ofWater {which will be relatively inexpensive. in manufacture and inoperation; which Will be simple and durable;

which will-prevent the vegetables and "the like from becoming Watersoaked, and becoming ruined thereby; which will be eflicientinaccomplishing all the purposes for" which it 'is'intended. i

In so far-as applicants know or can asceritain there are now no.portable vegetable sprays available Which maybe moved from place toplace within' or without'a store "and i so operated, free fromattachment'to awater tap. Such tapsare not alwaysa'vailable and evenwhen available..are not'alwa'ys located at pointsbest' adapted .to usefwith the usual spray." Usual device s provide a relatively heavy sprayof water.

Being self .contai ed, our portable spray may be readily positioned adjacent' a vege= table rack or flower standand moved as desired; Noplumbing or vvater pipes'are required. The spray from our devicebeingdelivered'in a fine vaporized mist,is, quite largely evaporatedin'theair. Such evaporation-is attendedlloy a cooling of'the'Fru'its,'"vegetables 'and cut flowers are preserved longer under thevaporized than 'under'the coarser spray.
